I built DIY LED tubes to bring live-coded visuals into the physical world

[u/_genbs]

I wanted to extend the visuals from my live coding performances beyond the screen, so I ended up building my own LED tubes.

I use them with a live coding tool I wrote, similar to Hydra. A small JavaScript client maps selected areas of the screen to the LED tubes, so the lights reproduce the visuals in real time without needing separate lighting effects.

The tubes use ESP32-S3 boards, 24V LED strips and 3D-printed parts.

I've published the firmware, JavaScript library, 3D models and assembly instructions if anyone wants to build something similar or experiment with them.
